Minnie's UTI

[Tubby & Peanut's Mom]

I don't know why she wouldn't be responding either, but if your vet can't give you a more definitive answer, I would get a second opinion quick! When Tubby had his UTI earlier this year, he responded to the antibiotics within 24 hours. He was still not peeing normal, but had at least stopped sitting in the litterbox and was much more calm and relaxed. Even with humans I believe antibiotics work within 24 hours. I also know there are different antibiotics out there, and kitties are like people in that some work better on certain kitties than others.

Then, sorry for not knowing this, but is Minnie a female or male? Males are much more prone to what Randi was referring to, but I know Ritzy had a bad UTI earlier this year too, that was possibly crystals. I'll have to see if I can find the thread and give you a link so you can see what worked for her.

But really, this is what bothers me most about your post
The doctor doesnt know why she's not responding to the medication..

Even if the doctor doesn't know, he/she should be doing something about it, or trying something different, not just saying well, I don't know...

Here's the link to the thread about Ritzy's UTI. Hope it helps!
